87864e7: Add count-aware pagination via page(). Each entity client now exposes page(query) returning { items, total, limit, offset } — the remote adapter asks PostgREST for Prefer: count=exact and reads the total from Content-Range in a single request; the mock adapter reports the filtered total. list() is unchanged. Generated clients (appsdk generate) now type page() alongside list().
